Improvement in spike-extractors



WILLIAM S.` HOUGH, OEJOHNSTOWN, PENNSYLVANIA.

Letters Patent 110,111,845, @ma February 14, 1871.

IMPROYEMENTIN SPIKE-EXTRACTQRS'l The Schedule ref erred to Vin. these Letters Patent and making Pani, of th? same' I, WILLIAM S. HoUGH, of Johnstown, in the conn# ty of Cambria and State of Pennsylvania, have invented a Machine for ExtractingRailroad-Spikes nsed for fastening railroad-bars to the sleepers orties on road-bed, ot' which the following is a specification.

Nata/re and Object-s of lInwentn.

My invention consists of the combination of a curved lever, of novel form, with a movable stand or' frame, of novel form, operating as a fulcrum, for the purpose of elevating and lowering a verticalbar which attaches itself, by means of an orifice or catch at the lower end, to the spike to be pulled ont, thus e'iecting-the extraction of the spike with greater case and" speed than by the hand-power now in use, and also enabling the operator, by inclination of the stand upon its curved bottom, in such way that the 'lifting power will be parallelv with the inclination of spikes driven in at an angle, to draw such spikeswithout curving or breaking them, and without injury to the tie.

Description of Accompanying Drawing. Figure 1 is 'a side elevation of my machine. l Figure 2 exhibits vertical bar,'with orifice or catch for catching the head of the spike to be pulled.

Figure 3 is a back view of stand and lever.

General Description a, in iig 1, is'the stand or frame, to be constructed of two ironplates, held together by bolts, indicated l by round dots, thus, o, broad at the bottom, to malte road-bed at M, is curved to the sides and ends so that it may be leaned to any` angle necessary to pullout a spike inthe direction in which it was driven in.

The stand is heavy enough to support itself, and

- may be carried readily by a man, or moved by the handle I.

The power is applied by meansof tbelever b, which moves upon the bolt I), g.1, as a fulcrnm, andplays through the vertical bar c at the orice K, thereby elevating and depressing it in a right line through the guides H H, which are a part of the stand or frame A.

A't E, in fig. l and iig. 2, is the orice and catch, in and on vertical bar c, which catches 'the head of spike to be' drawn.

' In fig. 2 c represents a front view of' the vertical bar, the dotted lines at the right of the figure at a. showing the foot of the stand, more fully shown in fig. 3, and the dotted lines at the left of the figure at b b `indicatingthe arm of the lever when raised, more fully shown at b in iig. 3. 4 yAt K is the oritice in the vertical bar, through which the lever b plays, and H H are the guides, being a part of the frame, which give direction to the vertical bar.

In fig. 3 A represents the stand or frame, shaded from M to L, to shoT how far it is solid,the space between the plate of the stand from L to L showing l the space through which the lever?) is operated upon the bolt and fnlcrum D.

Claim. p

Whatv I cla-im as myinvention, and desire to vse'- cure by Letters Patent, is

The combination of stand A, curved lever b, and vertical bar c, provided with orifice and catch E, all constructed as and for the purpose set forth.

W. S. HOUGH.
